    What pump (size & model)do you want to use , and for what purpose.

    In general they wont work due to the corrosive nature of salt water but I remember they do have a "all plastic" model

    My pool pump is a speck and its a salt water pool. Its also 450w so I guess you could use it. I recon it will work but electricity costs will be hectic

    They all use a steel spring and flange on the mechanical seal. I use a Magic 6 (my second one) and they rust.

    Nice, efficient high-head pumps, but you can't get away from the rusting unless you go mag drive.

    Hi!

    I will be using the badu 45, its 450W
    I will be replacing the mechanical seal
    with a silicon carbite and viton seal and
    the shaft will get a polliepropileen coating.

    Pumping 18000 l/h at a head of 2m

    Nice, Christo. Where are you getting that seal from? Price?

    Also, who's coating the shaft for you?

    Here's the regular mechanical seal that comes with the pump: M7N — EagleBurgmann - Rely on excellence

    Note the materials:
    Materials
    Seal face: Special cast CrMo steel (S), Silicon carbide (Q1, Q2), Aluminium oxide (V)
    Seat G9: Carbon graphite antimony impregnated (A), Carbon graphite resin impregnated (B), Silicon carbide (Q1*, Q2*)
    Seat G4: Silicon carbide (Q1*, Q2*)
    Seat G6: Silicon carbide (Q1*, Q2*)
    Seat G13: Carbon graphite antimony impregnated (A), Carbon graphite resin impregnated (B)
    Secondary seals: EPDM (E), NBR (P), FKM (V), FFKM (K)
    Springs: CrNiMo steel (G) Metal parts: CrNiMo steel (G), Duplex (G1)

    Does the one you're getting have any coating for the steel?

    Why not get yourself a Reeflo Barracuda that push also about 18000L/h at 165W
    More expensive to buy, cheaper to run.

    I priced these at Elite. Almost R10k a pump. I researched their mechanical seals. Lots of problems (also leaking/metal). No silver bullet, sadly.

    Either I can get a non-metal mechanical seal in the next year or so, or alternatively my replacement pump will be a mag drive pump (Iwaki, Pan World etc.).

    Rob for your volume of water you will not regret an Iwaki/Panworld -0.75kw minimum though

    Nope. You can import them yourself, like flappy, but after freight and taxes etc. they still wind up very expensive. At that price I'd definitely go for a Iwaki/Blue line/Panworld. Not as efficient, but very, very reliable.

    Hi Rob

    Yes! I've got some news! Not on the
    Costs but his got the seal I can use
    On the pump! The only problem is his
    Not 100% sure its the same fit! As I
    Dont know the exact spec's of the seal
    I will have to buy the pump and strip it
    to see!

    So I'm planing to buy it this mounth and
    Do all the mods i want to on it! I'm not in
    Much of a hurry for my system is not up
    And running yet! Was a long term project,
    Turned out to be a very, very long term
    Project!

    I'll post pics and progress of the mods as
    Soon as I Start!

    Cheers
